Does LookBack only work on debug builds?

[e-t-l]

LookBack uses the install -d command, which I believe only works on debug apk builds. And when I tried downgrading an app to a previous apk, it didn't work. LookBack kept showing a message about "adb restrictions in developer options." I don't know what that means but Shizuku is already unning and connected. LookBack won't proceed past xhoosing an apk in the file picker dialog.

It is not limited to debug builds. It's most likely that there are additional adb restrictions added by your device manufacturer, like "Permission monitoring" toggle found in Oppo roms, or "usb debugging security settings" toggle found in Xiaomi roms. You just need to find these rom-specific implementation in developer options and configure them in a way that there are no restrictions.
